Wheres the promised app update

The app has great potential. We were promised an update over a year ago from the developer. The update was supposed to include the ability to plot routes via distance and direction from any given chosen point the navigator chose.
Never happened.
As a tactician it needs to have the ability to plot maneuverability and give simple "x" your here, you need to go to "y" but maybe "z" to "y" is a better tactical option in your planning phase.
Currently.. you cant get there from here!
Needs that update as promised. However I believe they have abandoned ship!
